The neutral hydrogen structure at high galactic latitude . ... Angular structure of the interstellar HI emission at 21 cm was investigated on the declinations of +5 degree, +16 dg., +27.5 dg., +39 dg. and +50 dg. in the R.A. range of 10 h to 16 h (galactic latitudes from 45 dg to 90 dg) with the help of RATAN-600 radio telescope with mean angular resolution 2.0'x 20'. ... Angular power spectrum of interstellar HI emission was computed with standard FFT code and smoothed over 1 h along R.A. (figure 1). ...

RATAN­600 OBSERVATIONS OF MICROWAVE STRUCTURE OF THE QUIET SUN T.I. Kaltman, V.M. Bogod, A.N. Korzhavin, S.Kh. Tokhchukova Special astrophysical observatory of RAS, Saint­Petersburg, Russia arles@mail.ru To investigate microwave emission of the quiet Sun the observations with RATAN­600 from September, 2005 to March, 2006 in the range 6­16.4 GHz with the 1% frequency resolution were used. ... The spectra of brightness temperatures grow with wavelength. ...

... 1998: . The structure of neutral interstellar hydrogen emission at high galactic latitudes from 45 to 90 degrees was studied for the first time with the RATAN-600 at a wavelength of 21cm. The on galactic latitude dependence of the average characteristics of hydrogen distribution in the sky corresponds to the distribution of gas in the Galaxy in the shape of a flat layer. ...
